A brief discussion on WebSockets introduction and core architecture design

The HTML5 WebSockets specification defines an API that allows web pages to communicate with remote hosts in two directions using the WebSockets protocol. Introduces the WebSocket interface and defines a full-duplex communication channel over a socket on the network. HTML5 WebSockets offer a huge reduction in unnecessary network traffic and latency without the inability to scale polling and long polling solutions which are used to simulate a full duplex connection by maintaining two connections. HTML5 WebSockets account for network hazards such as proxies and firewalls, enable streaming over any connection, and are able to support upstream and downstream communications on a single connection. HTML5 WebSockets-based application servers reduce the burden and allow existing machines to support more concurrency. connect. The figure below shows a basic WebSocket-based structure, in which the browser uses a full-duplex WebSocket connection to communicate directly with the remote host. Applications typically use long polling for basic line defense firewalls and proxies. The technology is effective, but not suitable for application sub-500

Introduces the WebSocket interface and defines a full-duplex communication channel over a socket on the network. Html5 WebSockets provide a huge reduction in unnecessary network traffic and latency without the climb-polling and long-polling solutions being used to simulate a full-duplex connection by maintaining two connections.
